To find the graph of \( y = -f(x) \) given \( f(x) = (x+3)^2 \), we can follow these steps:
1. **Understand the original function**: The function \( f(x) = (x + 3)^2 \) is a standard parabola that opens upwards, with its vertex at the point (-3, 0).
2. **Transform the function**: The negative in front (\( y = -f(x) \)) indicates a reflection across the x-axis. This means every point on the graph of \( f(x) \) will flip to a corresponding point below the x-axis.
3. **Determine the new vertex**: Since the original vertex of \( f(x) \) is at (-3, 0), the vertex of \( y = -f(x) \) will be at (-3, 0), but it will open downwards.
4. **Sketch or identify the characteristics of the graph**: The graph of \( y = -f(x) \) will be a parabola that opens downwards, and it will look like a standard downward opening parabola with the same vertex at (-3, 0).
Look for the option that matches these characteristics—a downward-opening parabola that has its vertex at (-3, 0).
Without the actual image or specific options presented, you would identify which option corresponds to a downward-opening parabola centered at (-3, 0). Choose that option accordingly.
